Trying to run Waveshare 7'' display on my Pi4. According to Waveshare manual I should set params manually in config.txt:
[all] max_usb_current=1 hdmi_group=2 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0 hdmi_drive=1
Unfortunately I can't see whole screen. Only top, bottom and left side is visible. Touchscreen is hitched. When I press most top left corner few centimeters down and few centimeters right is affected.
How to solve this problem?
When I connect the same display to Pi3 everything goes fine.
